§OpenStack API bindings (SDK)
Every platform API requires SDK bindings to various programming languages.
OpenStack API bindings for Rust are not an exception. The OpenStack comes with
openstack_sdk
crate providing an SDK with both synchronous and asynchronous
interfaces.
API bindings are generated from the OpenAPI specs of corresponding services. That means that those are only wrapping the API and usually not providing additional convenience features.
§Features
- Sync and Async interface
Query
,Find
andPagination
interfaces implementing basic functionalityRawQuery
interface providing more control over the API invocation with upload and download capabilities.- Every combination of URL + http method + body schema is represented by a dedicated module
§Structure
Every single API call is represented by a dedicated module with a structure
implementing REST Endpoint
interface. That means that a GET
operation is a
dedicated implementation compared to a POST
operation. Like described in the
Structure document every RPC-like action and every microversion
is implemented with a single module.
§Using
The simplest example demonstrating how to list compute flavors:
use openstack_sdk::api::{paged, Pagination, QueryAsync};
use openstack_sdk::{AsyncOpenStack, config::ConfigFile, OpenStackError};
use openstack_sdk::types::ServiceType;
use openstack_sdk::api::compute::v2::flavor::list;
async fn list_flavors() -> Result<(), OpenStackError> {
// Get the builder for the listing Flavors Endpoint
let mut ep_builder = list::Request::builder();
// Set the `min_disk` query param
ep_builder.min_disk("15");
let ep = ep_builder.build().unwrap();
let cfg = ConfigFile::new().unwrap();
// Get connection config from clouds.yaml/secure.yaml
let profile = cfg.get_cloud_config("devstack".to_string()).unwrap().unwrap();
// Establish connection
let mut session = AsyncOpenStack::new(&profile).await?;
// Invoke service discovery when desired.
session.discover_service_endpoint(&ServiceType::Compute).await?;
// Execute the call with pagination limiting maximum amount of entries to 1000
let data: Vec<serde_json::Value> = paged(ep, Pagination::Limit(1000))
.query_async(&session)
.await.unwrap();
println!("Data = {:?}", data);
Ok(())
}
